Outline of Final Research Achievements

PHS1 was shown to phosphorylate Thr349 of alpha-tubulin, and the phosphorylated tubulin does not polymerize to microtubule polymer. In plant cells, the phosphatase domain suppresses the kinase domain of PHS1. In response to environmental stress (especially hyperosmotic stress), this suppression is cancelled and the kinase is activated. Liverwort and Chlamydomonas possess PHS1, which is activated by salt and hyperosmotic stresses. In vitro experiments with recombinant proteins show that PHS1 has basal kinase activity, which is directly inactivated by the MPK phosphatase activity within PHS1.
